from the drawings and are not described in this specification.

The capping mechanism may be of the type adapted to apply a screw cap it the neck of the bottle is provided with screw threads. Vilhere catsup bottles or the like are being filled, the capping device may be of the type adapted to apply crown caps. Certain aspects of my invention are broadly applicable to these and other types of cap applying devices, and it is to be understood that do not limit my invention to the particular type ot cap applying devices illustrated in the drawings. These cap applying devices,however, have a cap receiving recess in which the cap is disposed when it is applied to the bottle. The cap applying device is then actuated so Y as to apply the cap to a bottle, and again supplied with a cap by having such cap placed in the cap receiving recess. This `cycle is repeatedas often as a bottle is presented to be capped.

Tn the drawings, l have shown a crown` cap applying device including a spring pressed plunger disposed above a die block as is customary in crown capping machines. The die block has a lateral opening 28 (see F ig. through which. caps enter the cap receiving recess 29. Tn this form of capping device, the cap receiving recess is directly beneath the spring pressed plunger oi the capping device.

The chute 12 has a flexible portion which is connected to a curved portion 3G secured to the side of the capping device. The opening 28 is a lateral opening and, therefore,

caps .must be deflected. from their path downy the chute in order to enter the cap receiving -recess 29. The weight oit the column of caps in the chute 12 is taken by an abutment member 82 at the lower end of the curved portion 30 of the chute; and at this time the lowest cap in the chute is in line with the cap receiving recess 29.

I have provided mechanism for pushing this lowermost cap laterally from the chute into the cap receiving` recess 29. This mechanism comprises a swinging arm 33 having at its lower end ahead 34 for engaging the cap, this head being shown in broken. lines 1n A Fig. 2. This swinging arm is pivoted at 35 to a bracket 36. lts upper end is provided with arcrank 37 formed with an arcuate slot 38. A pin 39 which is supported by a bracket 49 extends into the slot 38'. The bracket 40 is carried by a vertical rod41. This rod is slidably mounted in lugs 42 and 4B- on the capping device. A. compression spring 45 extends between thelower lug-43 and the bracket and, therefore, tends to move the bracket 4() upwardly. This tendency of the bracket 4 0 to move upwardly biases the arm v38 -outwardly .from the capping device.

Downward movement oit the rod 41. forces the arm 33 inwardly to push a cap into the cap` receiving recess 29. The rod 41 is yieldably pressed downwardly relative to the capping device when a spring pressed plunger 47 engages the upper cross member 14. The plunger 47 is slidable within a bore 48 in the rod 41 and is pressed upwardly by a spring 49. The plunger 47 engages thecross member 14 when the capping device moves to its upper position away from the bottle which has just lbeen capped. When the capping device is lowered to apply a cap to the next succeeding bottle the plunger 47 moves out'of engagement with the cross member 14; and the spring 45 is then able to move the arm 33 outwardly so that another cap may move into position at the lower end ot the section 30 of the chute. When the cap within they capping device has been applied to the bottle, the capping device rises, bringing the spring pressed plunger 47 into engagement with the cross member 14. Thisylowers the bracket 40, swings the arm 33 inwardly, and causes 'the lowermost cap in the chuteto be pushed by the head 34 into the cap receiving recess 29.

As is apparent from Fig. l, the capping device is normally maintained in elevated position by a coiled spring 50 suspended by hook 51 from the upper cross member 14. The lower end oi the spring 50 is attached to a aw carrying member 53 of a trip clutch generally indicated by the numeral52. A pin 54 secures a rod 58to the clutch member 53, the rod 58 extending vertically along the axis of the clutch Amember 53. A threaded sleeve'55 surrounds the rod 58 and is slidable relative thereto; but normally the sleeve 55 is positioned as shown. in. Figs. 1 and 2 with its lower end bearing against the upper end of the clutch. member 53. By rotating the threaded sleeve relative to the capping device, vertical adjustment of the capping device is eiected; as the capping device comprises a portion which surrounds the sleeve 55 and threadedly engages the same. A.' lock nut 54a is provided for securing the capping device in adjusted position.

The clutch member 53 is provided with a central longitudinal bore 56 within which the upper end of a rod 57 is slidable. The rod 57 forms part of actuating mechanism for the y capping device. This rod 57 is reciprocated at a regular rate; and the trip clutch is provided with the purpose of causing the capping mechanism to reciprocate with the rod 57 when this clutch is tripped. The lower end oi the rod 57 is slidabley in a bearing 59. A block 60 provided with trunnions 61 is se-y cured to the lower portion of the rod 57 above the bearing` 59. The trunnions 61' are disposed in slots G2 in the two forks G3 on the end of a lever 64. The lever 64 has a pivoted .mounting 65. A shaft G6 rotatably mounted in bearings 67 carries a cam 68 'for actuating the lever 64. The lattervcarries ico CII

type or construction. c

proved capping vmechanism vhas the advantage that the saine is not actuated unless a bottley is delivered into position to be capped. This advantage is in part due toI the trip mechanism which causes the clutch to bring about actuation of the capping ldevice when a bottle is delivered beneath the capping device. A furtheradvant'age of my invention resides in the arrangement for capping a bottle immediately upon its delivery from a fillingmachine onto a support beneath the capping device. It will furthermore be understood that there is additional advantage in the provision of the automatic control for theactuation ofthe capping device in such an arrangement since a bottle' is delivered onto the support and immediately capped, and the capping mechanism does not again descend until the capped'bottle has been pushed out from beneath the capping device vby the delivery of the next succeeding bottle from the filling machine.

Certain advantages arising as a consequenceof the improvements I have provided ina capping device by my invention are not restricted to the combination of the capping device in the manner illustrated in the draw- .ings with a filling machine, `nor in fact with nism land the like, as used throughout the specification and claims are used generically .as terms of definition andk not limitations,

and are inclusive of closures, crowns and caps generally` regardless 4of their specific While I have illustrated and described one specific form ofbottle capping mechanism 'and one particular arrangement of bottle filling machine and bottle capping mechanism,
